DFCAB utilizes multiple storage vendors for various tasks, ranging from production servers to backup-to-disk and archiving solutions.

DFCAB uses Dell (Equallogic/EMC) storage for its production systems using RAID-10 disk redundancy. DFCAB also utilizes enterprise-grade storage systems using RAID-6 disk redundancy for backups and archiving.

All storage systems reside on their own network architecture which is inaccessible to any systems except those specified by DFCAB as appropriate for access, protected by multiple firewall layers and rulesets.


DFCAB support services are available 24/7 (24 hours per day, 7 days per week). DFCAB does not currently provide direct support to PowerFlow customers as it is a services provider for PowerFlow Solutions products.  Any and all PowerFlow Solutions support requests should be directed to PowerFlow Solutions and a representative of PowerFlow Solutions will act as the intermediary and point of contact in any scenarios requiring support services.


DFCAB has a multifold backup and DR system in place:

DFCAB performs nightly full backups of all machines as well as transaction log backups for database servers every 15 minutes. These backups are encrypted and maintained on a hot backup storage device for up to 60 days. DFCAB also archives these encrypted backups to a hardened archive storage device for a retention period of at least 1 year (with immutability). Finally, DFCAB also archives these backups to encrypted off-site immutable media and maintains these archives for a period of up to 6 months, achieving a true 3-2-1 backup scheme.

DFCAB hot-replicates all essential production machines to a secondary system six times daily for DR purposes (every 4 hours). DFCAB maintains the 6 most recent replicas of each server to facilitate the immediate recovery of a failed server up to 24 hours old.

DFCAB health-checks all backup data on a weekly basis to ensure its integrity, excepting the offsite archive media which is checked monthly.

DFCAB maintains a cold (offline) server in a secure secondary location which can be utilized in the event of a catastrophic loss of hardware at our primary location. DFCAB tests this server on a monthly basis by restoring the most recent offsite archive media and briefly testing to ensure the restored systems behave as expected.


DFCAB does not currently hold any certifications since it is a customer of its Data Center provider.  DFCAB’s Data Center provider is a SSAE 16 SOC 2 Type II certificate holder.

DFCAB will use commercially reasonable efforts to ensure that access to DFCAB’s Data Center facility space will be monitored and restricted at all times. Efforts to ensure security to the facility is maintained via security card, video surveillance and security vestibule controlled by the Data Center provider.

DFCAB will not allow any non-employee physical access to its systems and will work with its Data Center provider to ensure the that only those with the authority are given access to the Data Center DFCAB shares with other customers and that the DFCAB equipment is safeguarded via physical lock and surveillance.

Offsite backup rotation shall be allowed only to DFCAB employees per the physical access rules stated above.  Off-site data shall be maintained in a fireproof, locked container with physical access allowed only to those DFCAB employees.

DFCAB will make every reasonable effort to ensure that any Customer data is safeguarded via network controls by explicit firewall rules.

In a dedicated services environment, Customer shall provide PowerFlow Solutions with external IP addresses to be used in these firewall rules to allow/deny external network access, which will then be relayed to DFCAB, deployed and confirmed by PowerFlow Solutions.

In a shared services environment, there are no specific rules in place to keep other PowerFlow users from accessing Customer’s data since this is a shared platform.
